Abstract
Purpose: This article describes a procedure to increase the visibility of a palatogram using gothic arch tracing ink.
Materials and Methods: The palatal surface of a denture is painted with gothic arch tracing ink. A thin layer of alginate impression powder is sprinkled on a layer of petroleum jelly. The patient is instructed to vocalize. The tongue contact area can then be evaluated.
Discussion: This technique is easy, fast, accurate, inexpensive and readily available to clinicians. If the palatal form must be modified, the modified area is easily discriminated. The technique can be used during the trial placement, insertion or post-insertion appointments.
Conclusion: This simple procedure is effective for the evaluation and correction of the palatal form of waxed or completed dentures.
